BDHD-EZK-IN-G20 Metal Hemispherical Resonator Gyro

The hemispherical resonator gyroscope (HRG) is the most promising gyro technology today, with a strong trend toward replacing modern fiber optic, laser, and electrostatic gyroscopes. Its compact size, lightweight design, long service life, and high resistance to environmental factors make it ideal for extensive market applications. A metal hemispherical resonator gyroscope is a device that measures a carrier's angular rate by detecting the precession of standing waves. It uses a symmetric metal shell as the resonant structure, operates via electrostatic excitation and capacitive detection, and responds to input rotation through the Coriolis effect. When the carrier rotates, this effect induces a "rotational" perturbation in the vibrating mode of the metal resonator—the fundamental mechanism by which the HRG senses rotation. The BDHD-EZK-IN-G20 is a metal hemispherical resonator gyroscope characterized by its small size, light weight, high precision, robust shock and vibration resistance, and self-calibration capability. As an essential component for strapdown inertial navigation systems in aerospace, marine, and oil drilling applications, it is indispensable for critical navigation and guidance systems.
